Autoblog has asked for clarification from Porsche officials in Germany. The brand stopped selling diesel models in the U.S. in 2015, and it is offering the 2019 Cayenne with a gasoline engine and plug-in hybrid version, but “will no longer be offering diesel models in North America,” Porsche spokesman Luke Vandezande says.

Porsche on Tuesday published an FAQ about its recall last year of nearly 30,000 Cayennes equipped with 3.0-liter V6 diesel engines after it told German regulators it found potentially illegal emissions-cheating software. It is providing a software update free of charge to owners, and it offered a premium for owners who traded in their older-model Porsches fitted with outdated diesel engines.
